Hi,
Summary:
Can you direct me to a circuit or help me design a circuit that will turn one or more LEDs on.
My goal is to illuminate my daughter's 6 room, 4' high doll house with white LEDs.
Details:
I want to be able to wall mount miniature push-button switchs in each room so that she can push once to turn the room light on and push it again to turn the room's light off.
I also want to have a porch light that works the same way.
I plan to use a 9V DC (350 mA) wall wort to power the house.
The LEDs are rated at 3.0 to 4.2 V. Would I be correct in assuming that each LED would draw ~20mA? I plan to run them at 3.5 V so they're not too bright.
(Here are the LEDs that I'm purchasing: **broken link removed** )
I plan to:
Connect a 275R .25W resistor in series with each LED
Connect all LEDs in parallel to the power source
Thanks in advance for your time and help,
Patrick
